For Concrete
Please secure to concrete with 3/8 x 3” long wedge or sleeve anchors. Do not use Concrete or Blue Screws.

For Wood
If you have access under your wood deck, please mount additional 2×6 or 2×8 wood blocking between your floor joists directly underneath your deck surface. Then drill holes thru both your deck surface and the additional wood blocking and use 3/8 x 4” diameter bolts, washers and nuts to secure from the underside of deck. Do not use Wood Screws or Lag Bolts.

D. For vinyl posts, leveling donuts can be adjusted to compensate for uneven mounting surfaces. For aluminum posts, you can level the Surface Mount with stainless steel washers.

Option 2: Drill directly through concrete

If concrete is less than 4in. thick, you may want to attempt drilling directly through it as illustrated below.
